Information from five surveys of slash pine ( Pinus ellioitti Engelm. ) and loblolly ( Pinus taeda L. ) pine plantations in East Texas between 1969 and 1987 indicated that infection rates for fusiform rust ( Cranatlium quercuum (Berle) Miyabe ex Shirai f. sp. fusiforme) have increased to about 50~ for slash pine and are continuing to increase for loblolly pine to current levels of 10- I 5:t.
